This module helps alleviate some of those pain points by defining some helping hashes, functions, and regular expressions. CONSTANTS $IANA_REGEX_PORTS Regular expression to match any port, irregardless of which protocol it goes over. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $port =~ $IANA_REGEX_PORTS; # Won't match $non_port =~ $IANA_REGEX_PORTS; $IANA_REGEX_SERVICES Regular expression to match any service, irregardless of which protocol it goes over. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $service =~ $IANA_REGEX_SERVICES; # Won't match $non_service =~ $IANA_REGEX_SERVICES; $IANA_REGEX_PORTS_DCCP Regular expression to match any port that is known to work over dccp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $port_dccp =~ $IANA_REGEX_PORTS_DCCP; # Won't match $non_port_dccp =~ $IANA_REGEX_PORTS_DCCP; $IANA_REGEX_PORTS_SCTP Regular expression to match any port that is known to work over sctp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $port_sctp =~ $IANA_REGEX_PORTS_SCTP; # Won't match $non_port_sctp =~ $IANA_REGEX_PORTS_SCTP; $IANA_REGEX_PORTS_TCP Regular expression to match any port that is known to work over tcp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $port_tcp =~ $IANA_REGEX_PORTS_TCP; # Won't match $non_port_tcp =~ $IANA_REGEX_PORTS_TCP; $IANA_REGEX_PORTS_UDP Regular expression to match any port that is known to work over udp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $port_udp =~ $IANA_REGEX_PORTS_UDP; # Won't match $non_port_udp =~ $IANA_REGEX_PORTS_UDP; $IANA_REGEX_SERVICES_DCCP Regular expression to match any service that is known to work over dccp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience.

Case is ignored and the protocol must match on a word boundary! Examples # Matches $service_sctp =~ $IANA_REGEX_SERVICES_SCTP; # Won't match $non_service_sctp =~ $IANA_REGEX_SERVICES_SCTP; $IANA_REGEX_SERVICES_TCP Regular expression to match any service that is known to work over tcp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $service_tcp =~ $IANA_REGEX_SERVICES_TCP; # Won't match $non_service_tcp =~ $IANA_REGEX_SERVICES_TCP; $IANA_REGEX_SERVICES_UDP Regular expression to match any service that is known to work over udp. While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience. Case is ignored and the protocol must match on a word boundary! Examples # Matches $service_udp =~ $IANA_REGEX_SERVICES_UDP; # Won't match $non_service_udp =~ $IANA_REGEX_SERVICES_UDP; $IANA_HASH_INFO_FOR_SERVICE This maps a service and a protocol to the information provided to us by IANA. Examples # Get info for ssh over tcp $ssh_tcp_info = $IANA_HASH_INFO_FOR_SERVICE->{ ssh }{ tcp }; Dumper $ssh_tcp_info; # 22 => { # desc => 'The Secure Shell (SSH) Protocol' # name => 'ssh' # note => 'Defined TXT keys: u= p=' # } # Get info for http over any protocol $http_info = $IANA_HASH_INFO_FOR_SERVICE->{ http }; Dumper $http_info; # sctp => { # '80' => { # desc => 'HTTP', # name => 'http', # note => 'Defined TXT keys: u= p= path=', # }, # }, # tcp => { # '80' => { # desc => 'World Wide Web HTTP', # name => 'http', # note => 'Defined TXT keys: u= p= path=', # }, # }, # udp => { # '80' => { # desc => 'World Wide Web HTTP', # name => 'http', # note => 'Defined TXT keys: u= p= path=', # }, # }, $IANA_HASH_SERVICES_FOR_PORT This lists all of the services for the given port, irregardless of the protocol. An empty list will be returned if nothing is found. This respects wantarray> Examples my $port_22 = $IANA_HASH_SERVICES_FOR_PORT->{ 22 }; Dumper $port_22; # [qw/ ssh /] my $port_1110 = $IANA_HASH_SERVICES_FOR_PORT->{ 1110 }; Dumper $port_1110; # [qw/ nfsd-keepalive webadmstart /] $IANA_HASH_SERVICES_FOR_PORT_PROTO This lists all of the services for the given port and protocol. Examples my $port_22 = $IANA_HASH_SERVICES_FOR_PORT_PROTO->{ 22 }{ tcp }; Dumper $port_22; # [qw/ ssh /] my $port_tcp_1110 = $IANA_HASH_SERVICES_FOR_PORT_PROTO->{ 1110 }{ tcp }; Dumper $port_tcp_1110; # [qw/ webadmstart /] my $port_udp_1110 = $IANA_HASH_SERVICES_FOR_PORT_PROTO->{ 1110 }{ udp }; Dumper $port_udp_1110; # [qw/ nfsd-keepalive /] $IANA_HASH_PORTS_FOR_SERVICE This lists all of the ports for the given service, irregardless of the protocol.

If only the port is given, then it will be checked across all protocols while restricting the search to just the provided protocol if one is given. Arguments 1 Port * Required * "Port (int)" * Port you want looked up 2 Protocol * *Optional* * "String" * Limit the search to only this protocol if specified Returns 1 Search results * "Boolean" * 1 if the match was found, 0 otherwise Examples iana_has_port( 22 ); # 1 iana_has_port( 34221 ); # 0 iana_has_port( 271, 'tcp' ); # 1 iana_has_port( 271, 'udp' ); # 0 iana_has_service Helper function to check if the given service (and optional protocol) is defined by IANA. If only the service name is given, then it will be checked across all protocols while restricting the search to just the provided protocol if one is given. Arguments 1 Service Name * Required * "String" * Service name you want looked up 2 Protocol * *Optional* * "String" * Limit the search to only this protocol if specified Returns 1 Search results * "Boolean" * 1 if the match was found, 0 otherwise Examples iana_has_service( 'ssh' ); # 1 iana_has_service( 'not-ss' ); # 0 iana_has_service( 'xmpp-server', 'tcp' ); # 1 iana_has_service( 'xmpp-server', 'udp' ); # 0 iana_info_for_port Helper function to get the known services for the given port and optional protocol, as defined by IANA. If only the port is given, then you will get back an array ref containing all of the services that are defined by IANA. If a protocol is specified, then the returned prtocols will be limited to those running over that type. Arguments 1 Port * Required * "Port (int)" * Port you want looked up 2 Protocol * *Optional* * "String" * Limit the search to only this protocol if specified Returns 1 Search results * "Array" * The list of protocols running over the specified info (arrayref if in scalar context) * Undefined if the searched was unsuccessful! Examples iana_info_for_port( 22 ); # [qw/ ssh /] iana_info_for_port( 34221 ); # undef iana_info_for_port( 271, 'tcp' ); # [qw/ pt-tls /] iana_info_for_port( 271, 'udp' ); # undef iana_info_for_service Helper function to get the known information for the given service and optional protocol, as defined by IANA. If only the service is given, then you will get back a hash ref containing the normal return information hash for each defined protocol for that service. Arguments 1 Service Name * Required * "String" * Service name you want looked up 2 Protocol * *Optional* * "String" * Limit the search to only this protocol if specified Returns 1 Service information (for a provided protocol) * "Hash" * Undefined if the searched was unsuccessful! The returned hash contains the following pieces of information (keys are lower case): Name The full name (with proper capitalization) for the requested service Desc A short synopsis of the service, usually a sentence or two long Note Any additional information they wanted to provided that users should be aware of Examples iana_info_for_service( 'xribs' ); # { udp => { 2025 => { desc => '', name => 'xribs', note => '' } } } iana_info_for_service( 'not-ss' ); # undef iana_info_for_service( 'xribs', 'tcp' ); # undef iana_info_for_service( 'xribs', 'udp' ); # { 2025 => { desc => '', name => 'xribs', note => '' } } INSTALLATION See perlmodinstall for information and options on installing Perl modules.
